Software-Defined Deluge: Promises, Pitfalls And Players


Ever since the term "software-defined networking," or SDN, moved from geek status to become a widely recognized trend via VMware's monster $1.2-billion acquisition of SDN startup Nicira, the IT industry has been assaulted with talk of software-defined storage, software-defined compute, software-defined data centers and, well, software-defined anything.

Yet for all the talk, software-defined is real.

Turn the page to get a taste of the software-defined movement, starting with a look at what could happen to hardware vendors as well as a who's who in the industry.
